三、木材的化学加固用化学物质处理木材,以保持木材的基本形状,增加尺寸稳定性,提高耐损害能力和物理力学强度的方法,叫做木材的化学加固,这里专指对古建筑木结构和木质古文物的处理.最初人们对遭受损害的木材通常使用油脂和天然树脂等做加固处理.1945年开始,这些材料被迅速发展起来的人造树脂和塑料所代替.1950年聚乙烯醇被用于湿材的保护.1958年,用高分子单体浸注木材,并使在放射线作用下发生聚合作用,出现了木
3. Chemical reinforcement of wood The method of treating wood with chemical substances to maintain the basic shape of the wood, increasing the dimensional stability, and improving the resistance to damage and physical and mechanical strength is called chemical reinforcement of wood. Here, it specifically refers to the wooden structure of ancient buildings and Disposal of wooden artifacts. Initially, people used damaged materials such as grease and natural resins to reinforce the wood. Since 1945, these materials have been replaced by synthetic resins and plastics that have been rapidly developed. In 1950, polyvinyl alcohol was used. Protection of wet materials. In 1958, polymer monomers were used to impregnate the wood and caused polymerization under the action of radiation. Wood appeared.
